安装RVM后：

Question

昨天我在rails应用程序（v2.3）上使用ruby进行开发，并决定将我的iMac更新为OSX Mavericks。现在，每次我尝试在本地运行我的应用程序时，都会出现以下错误。有谁知道造成这种情况的原因是什么？

像这样运行：

script/server -e development

错误：

 /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- script/../config/boot (LoadError)
        from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require'
        from script/server:2:in `<main>'

脚本/服务器（文件）

#!/usr/bin/env ruby
require File.dirname(__FILE__) + '/../config/boot'
require 'commands/server'

安装OSX Mavericks之前一切正常。

我注意到的事情：

现在2.0中安装的ruby版本（以前是v1.8.7）

仅供参考：我还是铁杆的新手。

安装RVM后：

好的，我设置了RVM，并确保安装并配置了ruby（1.8.7）和rails（2.3.11）的版本作为默认值。

已安装的RVM：

curl -L https://get.rvm.io | bash -s stable --rails

安装Ruby 1.8.7：

rvm install ruby-1.8.7-p374

将v1.8.7设为默认版本：

rvm --default use 1.8.7

安装Rails v2.3.11：

gem install rails -v 2.3.11

从系统安装所有宝石

rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system

现在当我运行我的应用程序时，我收到以下错误:(我错过了什么？）

从这个问题中要理解的主要事情是，您不能依赖于ruby版本的操作系统或您在ruby项目中使用的gem。当您创建其他ruby应用程序时，您可能会再次遇到麻烦。

-  To manage the gems use Bundler
   Bundler maintains a consistent environment for each ruby applications. 

-  To manage the Ruby versions use rbenv or rvm

OSX Mavericks之后无法加载此类文件 - 脚本/../config / boot（LoadError）
